How to resize a button depending on its text
Solution 1
Your best bet is to set the AutoSize property as described ach's answer
However if AutoSize isn't working for you, resizing the button in code is easy enough. You can just need to set the button's width. The trick is making it big enough to fit your text.
using(Graphics cg = this.CreateGraphics())
{
SizeF size = cg.MeasureString("Please excuse my dear aunt sally",this.button1.Font);
// size.Width+= 3; //add some padding .net v1.1 and 1.0 only
this.button1.Padding = 3;
this.button1.Width = (int)size.Width;
this.button1.Text = "Please excuse my dear aunt sally";
}
Solution 2
There's absolutely no need to use the underlying Graphics
object as the other posters have said.
If you set the button's AutoSize
property to true, the AutoSizeMode
to GrowAndShrink
, and the AutoEllipsis
to false, it will resize automatically to fit the text.
That being said, you may need to make several layout adjustments to make this change fit into your UI. You can adjust the button's padding to add space around the text, and you may want to place your buttons in a TableLayoutPanel
(or something) to stop them from overlapping when they resize.
Edit:
@mastro pointed out that: AutoEllipsis
is only valid when AutoSize
is false
(As explained in the documentation), so it can be safely ignored as long as the other three properties are set correctly.
Solution 3
Try this:
Button.AutoSize = true;
Button.AutoSizeMode = System.Windows.Forms.AutoSizeMode.GrowOnly;
Button.TextAlign = ContentAlignment.MiddleLeft;
Button.Padding = new Padding(0, 0, 0, 0);
Solution 4
To enable a Button in WinForms grow and/or shrink depending on the size of the Text, you need to set the button's AutoSize
property to True
and the AutoSizeMode
property to GrowAndShrink
.
// C#
btn.AutoSize = true;
btn.AutoSizeMode = AutoSizeMode.GrowAndShrink;
' VB.NET
btn.AutoSize = True
btn.AutoSizeMode = AutoSizeMode.GrowAndShrink
Please note that the AutoSize
property will only allow the button's size to grow if the AutoSizeMode
property is set to GrowOnly
; by changing the AutoSizeMode
property to GrowAndShrink
, the button will now automatically extend or reduce in width and height based on its Text
property.
Also note that in setting the two properties as shown above, you can make use of new lines (Environment.NewLine
or vbCrLf
) in the Text property and the button will scale down as needed.
Solution 5
In addition to setting the AutoSize
to true
and the AutoSizeMode
to GrowAndShrink
, as suggested in the other answers, you may also need to set the TextImageRelation
property, if you have set the button image, so that the text doesn't overlap the image.

In the process of translating an application with C# + Winforms, I need to change a button's text depending on the language.
My problem is the following :
Let's say I want to translate a button from "Hi all!" to "Bonjour tout le monde" !
As you can guess, the button's size won't be the same if I enter english text or french one... My question is "simple", how can I manage to resize the button on the fly so the text fits its content in the button ?
So far I got something like that !
